BEWARE OF FALSE ADVERTISING

We have purchased a battery on 13/01/2021 which was suppose to have a guarantee for 12 months - The battery is faulty, we returned it back to Infinity last week, only to be told we damaged the battery and they cannot replace - How convenient to now blame us for it so they d not have to replace it before the warranty has expired - We have purchased many batteries from Infinity and this is the worse service we have EVER HAD - BLAMING THE CUSTOMER SO YOU DO NOT HAVE TO REPLACE IT UNDER WARRANTY IS EXTREMELY UNPROFESSIONAL
